I didn't have a lot of experience with XBox 360. I was lucky enough to buy slightly used PS3 with Move package, chargers and 3 DualShock controllers for an awesome price. I have to tell you that XBox controllers look bulky too me as opposed to convenient and responsive DS3 controllers from Sony. Also, if you get a premium Sony membership - you'll get additional perks.
I'd go for PS3.
